Really ya want both, A site where there is exsiting turf we use the pipe puller and in 4 days you cant tell we were even there. However on new construction sites a trencher will save you time cause everything will be exposed. It will cut down on the hand digging big time.

Three options you can check out with Vermeer.
LM-42 which will be similar in size to the 410. The LM-25 smaller brother to the LM-42 with great productivity and if you want to go to the tool carrier route check out the S600TX with vibratory plow. It has the same shaker as the LM-25.
All of the machines listed above come with a vibratory plow and a trencher attachment if desired . An option for a boring attachment is also available. Check out the website link above.
